hello a newbie here, working on my 12-14th or so batch. From time to time I have an odd flavor creep into a beer. Is there a chart or list of flavors that correlate to a problem? For instance, read the a banana flavor is a sign the beer fermented at too high of a temp.

Welcome to the fourm! I'm not aware of a chart per se, but here is a link to a list from John Palmer's book How To Brew. While the entire book is available on line I would suggest buying a hardcopy. IMO it's one of the best books out there for brewers at all levels.
